You offspring of snakes, how are you, being evil, able to say good things? because out of the heart’s store come the words of the mouth. The good man out of his good store gives good things; and the evil man out of his evil store gives evil things. And I say to you that in the day when they are judged, men will have to give an account of every foolish word they have said. For by your words will your righteousness be seen, and by your words you will be judged. (Matthew, 12:34-37)
